TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGE DEWEY, of Blooming Valley, in the county of Crawford,4and State of Pennsylvania, have invented new and useful Improvements in` Combined Heating and Cooking-Stoves; and I do hereby declare the following to be a full and correct description of the same, suilcient. toA enable others skilled in the art to which my invention appertains to fully understand and construct the same, reference being had to the accompanying drawings, which make part of this specification, and in which- I Figure I, sheet 1, is a perspective view of my improved stove.

Figure 2, sheet: 2, is a vertical longitudinal section of the same.

Figure 3, sheet 3, is a top view of the same.

Figure 4, sheet 3, is a sectional plan in the line a: fr, fig. 2.

Figure 5, sheet 4, is a side elevation, .and

Figure 6, same sheet, a plan view, showing the application.

Similar letters of reference indicate corresponding parts in the several figures.

The nature of my invention consists in providing a cooking-stove with asteam-jacketand boiler allarournd the saine, und in peculiar means of using the steam for cooking and heating purposesboth.

A, in the drawings, may represent the top plate of a cooking-stove. This stove is provided with a 'lireplace or box, B, around which is a. steam-jacket, C, ending in a boiler, D, at the rear of thcirc-box, communieating with the part E of the jacket situated under the lire-box by means of holes e, similar holes allowing this part E to connect with C. Fines F communicate the fireplace B with the port G of the stove, a. damper, F', regulating the cxit oi' the products of combustion to the pipe'G. H is a double-walled bake-oven, the space between the two walls communicating at the forward end withl the iire-box B, ancLat the rear end port (l. Ill ,is acliding damper, operated by .the handle H2, kby means of which communication with either the fire-box A or' boiler D may be shut off from the bake-oven H. A hollow grate, I, made of tubing, rests on beads I in .the

bclreeovn, and connects with the steam-jacket C by means of the pipe I2, which is provided with u. stop-cock. Jmepresenthollow grate-bars, connecting in the rear with the boiler D, 'und closed in front by scrcwcnps J. K K- rcpresent two try-cocks in the front end of the steam-jacket C, by'means of which the height of thc water in the same and boiler may be ascertained. L represents evolve through which water is filled into the jacket C and boiler Bf M represents a. safety-valve of any common construction to vgive warning' when the Water is low and the pressure of the steam gets too strong, when it maybe'd'rawn oit by any 'of the stop-'ccclzson the jacket or boil-cr. N is an 4elastic vsteam-tight tube, the metallic end Nl of which passes through a. hole in the projection N2 into the bake-oven under thevgrat'c I, its other end connecting with either a stop-cock, O, near the top of'thc boiler D, or the spout of the tea-kettle O. The rear end of the gratcl communicates with a pipe, P, which passes upward, as shown in iig. 5, through the wall, passes along the wall backward and forward n few times, as shown at l, back through the wall into the stove pipe G1, upward through the saine in o coilthrough' the wall into the room above, around the room, as shown in iig. 6, back into the stove pipe, and so on, the stove pipe G1 passing straight upward through the house. vThe fire-box being entirely surrounded by water except at the front, and provided with tlues F, passing through the boiler D, the water will rapidly heat as soon as the fire is made, the gratebars J being also filled with water from the boiler D. The'steam, which is soon raised, passes through the pipe I2, hollow grate I, and pipe I,through the pipes in the different rooms, and as these pipes, after running around one room', pass again into the stove pipe or chimney through whichr the products `ofthe combustion escape, these latter again heat-thestcam in the pipes as it passes through their coils into tlrc` next room which it is intended to heat. Thus the rooms of awhole house may be heated by means of the steam from the cook-stove. My invention will be especially applicable to the small houses on the western farms, in which the chimneyY is situated in the centre of the house, and rooms are on each side of it. The products of combustion pass through the dues F into the port Gr and stovepipe G, when 'it is not desired to use the bakeoven, the damper F beingl opened and the damper H closed by its being pushed over the fireplace. If itis desired to use the bake-oven, the damper F is closed, and the damper'H placed either entirely over the port Gl of the stove, or, if the full heat is desired to he used, in such position as to nllow both openings oi' the bakc.

oven to be free. In this case the damper G in the pipe arm G3, connecting the bake-oven with the pipe Gx is closed, when tlie heat and smoke pass around the bake-oven througlrthe port G into the stove pipeG. Additional heat is given by the steam passing through the grate J. To' prevent lthe articles which are baking from burning, steam may be blown into the bake-oven by means of the pipe N attached either to a stop-cock on the boiler D,- or, if it is not desirable to take the steam from the same, to the spout of the tea-lchelte,*asr shown in dotted lines in fig. 1.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, i`s

l. A cook-stove provided with awater and steam-jacket around the sides, back, and bottom of the fire-box, substantially as'and for the purpose described.

2. The combination of the hollow grate-bars J with the Water and steam-jacket, as described, substantially as and for the purposes set forth. i Y

3. The heating pipe P, with its bent part I, which latter forms a shelf` in the bake-oven H, and supplied withsteam from the boiler D, arranged and operating substantially as described.

4. The pipe Gl, P, and P2, arranged substantially as described, and the latter connected to the steam-jacket of the cooking-stove for the purpose of heating the rooms by means of the cooking-stove. i

5. Passing the pipe through which the steam is led into the different rooms, in the shape of a coil, through the chimney or stove pipe, after leading it around one room and before passing it into the next, substantially as described. v

6. The elastic pipe N attached to either a stop-cock on the boiler Dor the spout of the tea-kettle, andleadin'g into the bake-oven, substantially as and for the purposes described. p

7. The eombination and arrangement of the {ire-'box B, pipes F, portG, pipe G G3, and hollow bake-ovcn H, substantially as and for the purpose described.

The above specification of my improvement in cooking and heating-stoves signed this 22d day of, Marcli,r1867t GEORGE DEWEY. Witnesses:
